This is my first post and hopefully an easy question...
Newbie alert: Very interested in casting my own boolits but to date my total number made is zero.
I have lots of plumbers lead, a small amount of Wheel weights and 100 lbs of 63/37 bar solder.
Been looking at the charts/curves for hardness of lead alloys and it seems that I can get the same hardness at least two different ways.
One is Tin + Lead and another is Tin + Lead + Antimony.
I don't have any antimony.
What are the pros and cons to just using tin + lead for 9mm?
